PP1 — Triticum turgidum subsp. durum

Summary

TRITD6BV1G223180 (symbol PP1, also known as TtPP1) on durum wheat chromosome 6B encodes a protein serine/threonine phosphatase catalytic subunit belonging to the PP1 family, with annotated protein phosphatase inhibitor, auxin efflux transporter, and transcription coactivator activities. This gene is associated with diverse biological processes including auxin export, regulation of epidermal cell division, leaf and cotyledon morphogenesis, trichome differentiation, root hair tip growth, gibberellic acid homeostasis, and responses to abscisic acid, chitin, and red light. It is linked to traits such as leaf and vascular morphology, root epidermal cell length, adventitious root number, shoot system elongation, bacterial blight resistance, seed set, temperature stress response, phototropism, and male sterility. The encoded protein localizes to the protein phosphatase type 1 complex, basal and apical plasma membrane, vacuole, nucleolus, and plasmodesmata.
